摘要: Thermal design and optimization for reverse water gas shift (RWGS) reactors is particularly important to fuel synthesis in naval or commercial scenarios. The RWGS reactor with irreversibilities of heat transfer, chemical reaction viscous flow studied based on finite time thermodynamics entropy generation minimization theory this paper. total rate (EGR) the different boundary conditions minimized subject specific feed compositions conversion using optimal control theory, configurations obtained are compared three reference linear, constant reservoir temperature flux operations, which commonly used engineering. results show that a drastic EGR reduction up 23% can be achieved by optimizing profile, inlet length simultaneously, linear temperature. These efforts mainly reducing irreversibility transfer. Optimal paths have subsections relatively thermal force, force local EGR. A conceptual sandwich structure compact modular proposed, without elaborate tools excessive interstage equipment. provide guidelines designing industrial
